Product Description and Application
4J33 is also known as Alloy 33
4J33 is constant expansion ceramic teal alloy, which is a ceramic sealing alloy developed on the basis of our ceramic characteristics. The linear expansion coefficient of the alloy is similar to that of 95%Al2O3 ceramics in the temperature range of -60℃ ~ 600℃. It is mainly used for matching sealing with ceramics,which is an important sealing structural material in electric vacuum industry.
